Detailed explanation of Ethereum (ERC20) Tokens

What is an ERC20 token?

ERC-20 first emerged back in 2015, and since then it has helped in the production of fungible coins for erc20 token development -based applications or protocols. Tokens created under the terms of this standard are the base cryptocurrency issued using the blockchain.

A unit of a coin can be easily replaced by another unit of the same coin, for the reason that they have the same value.

For example, the loss of a SAND unit will not be difficult to replace with a new SAND unit. Thus, the above tokens can be exchanged on a 1:1 basis. It does not matter which SAND coins the holder owns, as their value will always match all other SAND.

Additional parameters of ERC20 tokens

It is noteworthy that in ERC20 format tokens it is possible to set several auxiliary parameters, including:

Name — the name of the coin being created.

Symbol is a picture that will become the “business card” of the new cryptocurrency.

Decimals — number of decimal places (standardly there are 8).

If a developer wants to create his own digital currency that will be useful to the cryptocurrency market, then he will have to carefully study all the details, for the reason that there is a risk of vulnerability of the coin, which can arise from just a single error in the written code.

Among other things, scammers will be able to steal funds from token holders without hassle.

Often, tokens are created primarily to attract investment for a project. Depending on the goals of the project, developers assign various types of tasks to the digital currency:

security — providing holders with the right to take part in the development of a startup, vote, etc.;

individuality — providing the holder with a share of profits, private privileges or access to special privileged services;

usefulness — access to exclusive items or platform functionality.

How ERC20 tokens differ from others

The market for digital forms of money presently has a huge range of computerized monetary standards. Nonetheless, a tiny level of them work in accordance with the worldwide standard. Thus, since it is now so obvious what ERC-20 is, dealers may be thinking about how it varies from different tokens.

The primary differentiation is that each coin that has been “normalized” is associated with the Ethereum organization. Besides, in light of the fact that every cryptographic money has an extraordinary code, they are totally conveyed through Ethereum tasks and follow a particular location structure.

Cryptocurrencies have the following features:

  • they can be mined;
  • do not become bonus offers;
  • Every miner can become an issuer.
  • ERC20 tokens:
  • become bonuses for goods;
  • do not have a separate blockchain;
  • manage smart contracts;
  • The issuers are the developers.

TOP wallets suitable for working with ERC20

For anyone searching for a good ERC20 token wallet, this list is worth taking a closer look at. This comprises the most widely used bitcoin wallets in this particular market.

Numerous electronic wallets are available in the current digital finance sector for the storage of virtual money. The content provides links to some of the easiest digital wallets to use with ERC-20 standard coins:

  • Atomic wallet;
  • Metamask;
  • MyEtherWallet;
  • Trezor;
  • Trust Wallet.

Let’s Look at each and every detail of them.

Atomic wallet

It is a cross-stage decentralized wallet that can uphold around 300 monetary forms. An exceptional benefit is the inherent moment exchanger with the chance of getting cashback. There are variants for both portable and PC gadgets. Specialized help answers rapidly. Curiously, the wallet has its own coin of a similar name — Nuclear Wallet Token; marking it carries extra benefit to the proprietor.


A digital money wallet that gives admittance to all DeFi applications (like exchanging or NFT stages). An association with any dApps is laid out in no time flat. Specialists urge introducing the program variant, in light of the fact that the portable adaptation actually has an excessive number of deficiencies. The default network is Ethereum, yet there are a few others accessible to browse, exchanging between them at the moment. The ERC20 Metamask wallet is confined in Russian.


The program wallet is planned explicitly for coins in light of the Ethereum blockchain. It is sought after because of the shortfall of compulsory establishment and straightforward activity.

This is a phenomenal decision for new brokers who fear committing an error by getting befuddled in a complicated connection point. The wallet upholds NFTs, decentralized applications and stablecoins. The confidential key isn’t shipped off the ERC-20 organization, yet is put away on the client gadget. There is similarity with equipment wallets like Record and Trezor.


An equipment wallet intended for cold capacity of assets. This actually intends that there is a compelling reason needed to keep it continually associated with the gadget. Until it is associated, aggressors can not get to the digital money.

It is feasible to complete secure exchanges regardless of whether the PC gadget is contaminated with an infection. Upholds around 1.5 thousand coins and is likewise viable with numerous hot wallets.

Trust Wallet

Wallet for cell phones with true help for the Binance digital currency trade , joining with the Binance DEX stage is accessible. The virtual wallet upholds participation with DeFi applications and marking of specific digital currencies.

It has its own program for working with decentralized applications. For this situation, all keys are put away on the client’s gadget. As on account of Nuclear wallet, the wallet can offer the client a local badge of a similar name.

Benefits of ERC-20 tokens

Traders who have previously concentrated on ERC-20 tokens realize that these coins acquired their ubiquity on purpose. They enjoy many benefits, including the accompanying:

Demand. Today, both the ERC-20 standard itself and its digital currency are sought after on many exchanging stages. This is to a great extent because of the flexibility of the convention, which can adjust to various trade tasks.

Flexibility of settings. Engineers have the potential to empower works like programmed renewal of ETH for impending exchanges, freezing and thawing of coins, and considerably more.

Low level of fraud. All cryptographic money exchanges should be endorsed before execution. The complete number of coins improves on the confirmation methodology and guarantees that there are no copies available for use.

Development planning. The ERC-20 standard furnishes makers with a substantial strategy that will permit them to do their work without significant exertion.

Easy to use.ERC-20 coins are not difficult to work with. Brilliant agreements for this situation are written in the computerized language Robustness, which is suggestive of JavaScript. In addition to other things, makers can code contracts utilizing the Vyper language, which is like Python.

Standardization of coins. Ethereum gives coins that additionally incorporate standards for communication with other digital currencies and rules for obtaining. Through ERC, clients can move tokens into a wallet and start exchanging right away.

Degree of liquidity. Assuming undertakings that depend on the Ethereum blockchain are dynamic, this draws in additional clients to the organization. Also, with the appearance of ERC-20, it has become a lot simpler to trade coins.

ERC-20 can acquire the situation with the most well known norm among engineers all over the planet, yet it additionally has a few inconveniences.

Disadvantages of ERC20 tokens

In spite of the relative multitude of benefits recorded above, coins made by the ERC20 standard can’t be called totally great. They likewise have negative sides that ought not be neglected:

Large commissions. The coins depend altogether on the Ethereum blockchain, so every digital money exchange brings about an ERC20 expense, which expands as the degree of action on the blockchain increases.

Irreversibility of operations. Assuming the client sent coins to some unacceptable spot, the exchange can’t be switched. The equivalent can be said about cryptographic money that was taken by programmers; a striking model is the DAO hack.

Instability. Quite recently, in the ETH 2.0 update, the Ethereum blockchain changed the agreement technique from the PoW to PoS framework. In spite of the fact that Ethereum means to settle versatility issues, this will take a lot of time, during which the framework gambles becoming unsound. In addition to other things, individual coins can be taken out when utilized as installment for shrewd agreements.

Low speed of operations. Moves and withdrawals of assets are completed by means of the blockchain; assuming that the ERC20 network is under weighty burden, all activities are delayed. Right now, an exceptional answer for this issue is being grown, however the last finish of the work is still far away.

Errors during transmission. There are two kinds of records on this blockchain. The first is outside (EOA), which is constrained by confidential keys. The second is legally binding, which has a place with the agreement code. Moving coins from one EOA account is without bother. Yet, shipping off the agreement account actually falls flat with mistakes, which lead to unavoidable misfortunes of assets.

The entry threshold is too low. As indicated by pundits, anybody can make a digital currency, even without explicit objectives. Subsequently, this “proviso” can be utilized to sort out pre-deals of fleeting tokens and foster coins related with activities of no genuine worth.

Most arrangements are pointed toward disposing of these issues, however this takes time.

Until the disadvantages, particularly those that might include tricksters, are tended to, financial backers ought to consider them while assessing a specific ERC-20 token.

What alternatives are there to the ERC20 standard?

In addition to ERC-20, several other ERC standards cannot be ignored. They have similar features, but each has its own goals:

ERC-223 . Designed to reverse fraudulent transactions in ERC20 smart contracts. Informs clients about the cancellation of the transaction whenever it is discovered that the transfer was carried out without the direct participation of the client. But paid commissions cannot be returned. In addition, the standard is compatible with a very limited number of wallets.

ERC-721 . Tokens of this standard are non-fungible. Thus, each token itself is unique and rare, which determines its value. Details also affect the cost. For example, there are NFT collections presented in a strictly defined quantity. Tokens of this standard prevent the occurrence of counterfeits and inspire more confidence in potential investors.

ERC-777 . Positioned as a new version of ERC20. It has similar features to this standard but differs in that it offers the ability to create and burn tokens, as well as speed up transactions.

Key opponents and analogues of ERC20

It would not be amiss to mention several other standards that may well compete with the ERC20 standard.

Cardano. Blockchain written in Haskell has increased error resistance. It is being developed as a progressive decentralized platform for smart contracts with the most modern set of functions. The network turnover often exceeds Ethereum. It is known that a special “bridge” is being created to transfer ERC20 tokens to Cardano. This could create a problem for Ethereum in the future in the form of customer churn.

VER20. This is the coin standard of the Binance Smart Chain network. It has advantageous differences from the Ethereum blockchain in the form of accelerated trading operations and small commission charges. It has an extensive ecosystem, which also includes various DeFi projects. 7 out of 10 new decentralized application clients choose Binance Smart Chain with BEP20 coins.

TRC20 . Refers to the Tron project, which was originally created on Ethereum, but later moved to its own separate blockchain. During the pre-sales for the new decentralized platform, it was possible to collect about $70 million. It is noteworthy that smart contracts and coins according to the TRC20 standard, created in Tron, are absolutely compatible with Ethereum. Also, it is worth mentioning the Tether ERC20 cryptocurrency — a coin of the Tron project, created on the basis of Ethereum. The Tron blockchain has better scalability and offers better fees. Some experts suggest that this network will take a leadership position in the dApps segment in the near future.
